It's a problem, but not nearly as bad as many make it out to be. The ice caps are not going to melt enough to flood somewhere thousands of miles away from the poles, or even close by-at least, not anytime soon, as many people rich enough to buy seafront property are well aware of. Temperatures are rising slightly on average, but it's not going to be tomorrow when people start dying en masse of heat exposure. Or next year. There is ample time to address these issues. Drastic measures are not necessary. In some cases, it might actually be beneficial to do nothing at all, as warmer climate brings many benefits. Realizing this, I find the actions of people like Greta Thunberg amusing, and a bit ridiculous. She speaks of imminent apocalypse, as have many others over the years, but none has come, and none will come. Given time-and there is plenty of it-humanity will solve the problems arising from warmer temps without pulling the plug on industry and technology.
